STs are small, single-peptide toxins that include two unrelated classes: STa and STb, which differ in both structure and mechanism of action. Only toxins of the STa class have been associated with human disease. The STb toxin is associated with animal disease. ...
A low-molecular-mass, heat-stable enterotoxin, characteristic only of the virulent strains of Y. enterocolitica. Structurally and functionally homologous to the heat-stable enterotoxin of ETEC. ...
